SLIDER CLIP AND PHOTOVOLTAIC STRUCTURE MOUNTING SYSTEM
FIELD OF THE INVENTION
[0001] Embodiments of the invention relate to the field of
photovoltaic (PV)
power generation systems, and more particularly to a system and method for
simplifying
installation of PV structures at an installation site.
BACKGROUND OF THE INVENTION
[0002] Photovoltaic power generation systems are currently constructed
by
installing a foundation system (typically a series of posts), a module
structural support frame
(typically brackets, tables or rails, and clips), and then mounting PV
modules, also known as
solar panels, to the support frame. The PV modules are then grouped
electrically together
into PV strings, which are fed to an electric harness. The harness conveys
electric power
generated by the PV modules to an aggregation point and onward to electrical
inverters.
[0003] Conventional methods and systems of mounting a PV module to a
rail or
other structural support frame typically uses four module edge clips with
rubber inserts that
must be screwed into the rail in the field in parallel with installing the
module on the rail.
These methods and systems require screwing the clip halfway down, setting the
upper and
lower PV modules associated with the clip in place, and final tightening of
the clip screw to
secure the module to the rail. This process of handling the clips, half way
setting the clip,
setting the PV modules and finally tightening the clips is slow and labor
intensive.
[0004] With innovations in PV cell efficiency quickly making PV-
generated
energy more cost-effective, demand for large-scale PV system installations is
growing.
1

CA 02717691 2010-10-15
Such systems may have a row length of half a mile or more of installed PV
modules.
Accordingly, a simplified and cost effective system for PV module installation
is needed.

DETAILED DESCRIPTION OF THE INVENTION
[0024] In the following detailed description, reference is made to the
accompanying drawings which form a part hereof, and in which is shown by way
of
illustration specific embodiments that may be practiced. These embodiments are
described
in sufficient detail to enable those skilled in the art to make and use them,
and it is to be
3

CA 02717691 2010-10-15
understood that structural, logical or procedural changes may be made to the
specific
embodiments disclosed.
[0025] Described herein is a mounting system and slider clips that
support
simplified installation of photovoltaic (PV) structures. The mounting system
comprises a
support structure which can be mounted to support columns via an optional tilt
table. The
support structure comprises a plurality of parallel spaced beams and a
plurality of parallel
spaced rails that are mounted perpendicular to the beams. Disclosed
embodiments describe a
collapsible support structure in which the rails are pivotally mounted to the
beams. Rails are
preassembled with slider clips for holding edge portions of the photovoltaic
structures and
allowing for easy slide in insertion of the photovoltaic structures into the
slider clips. Rails
can also be integrally formed with slider clips. The mounting system maximizes
the use of
prefabricated and preassembled components and reduces the on-site field labor
costs
associated with installing the PV structures. Described herein are also
methods of installing
one or more photovoltaic structures using the mounting system and methods for
manufacturing slider clips and a photovoltaic structure mounting system.
[0026] FIG. 1 is a perspective view of a mounting system 300 with
installed PV
modules 100 in accordance with an example embodiment described herein. System
300 has
a plurality of PV modules 100 mounted on a support structure 200. A
prefabricated
frameless PV module 100 is typically comprised of a top layer, a bottom layer,
an array of
PV cells positioned tightly between the top and bottom layers and ancillary
elements such as
a PV generator junction box. The PV cell can be a solar cell made of thin-
film, silicon or
any other material for capturing solar radiation and converting the solar
radiation into direct
current (DC). The front and back sheets are typically made of glass or other
transparent
material to provide structural support and protect the PV cells from
environmental hazards.
Since each PV cell captures only a small amount of solar energy, multiple PV
cells are
electrically connected together to form a PV module 100. A plurality of PV
modules 100
can be grouped together and installed on-site to achieve a desired voltage and
current.
Although the embodiment described herein applies to a PV module 100 with
dimensions of
4

CA 02717691 2010-10-15
, .
approximately 48 in x 24 in, it will be readily appreciated by those skilled
in the art that the
disclosed embodiments may be modified to support PV modules with other
dimensions such
as, for example, 24 in x 12 in and 48 in x 48 in. Also, although the PV module
100 is
described as frameless, the various embodiments described herein can be
adapted for framed
PV modules as well.
[0027] FIG. 2A is a top view of the PV module support structure
200. In this
example embodiment, rails 220 and beams 210 are approximately 6.5 feet and 20
feet in
length, respectively. Rails 220 are mounted on beams 210 at alternating
distances of
approximately 27.50 inches and 20.50 inches apart. It should be appreciated
that while FIG.
2A illustrates a support structure 200 having ten rails 220 mounted on two
beams 210, the
embodiments are not so limited in the number of rails and beams. It should
also be
appreciated that rails 220 and beams 210 can be manufactured for any length
depending on
the array size and size of the PV modules to be mounted.
Support structure 200 includes a plurality of parallel spaced rails 220
pivotally
connected to one or more parallel spaced beams 210 by fasteners 230, such as a
rivet or any
other suitable connector which allows rail rotation, at each point of
intersection. FIG. 2A is
a top view of support structure 200 arranged in an installation configuration
whereby the
rails 220 are approximately perpendicular to beams 210. Support structure 200
can collapse
at the pivot points into a folded configuration in the manner shown in FIG.
2B. Support
structure 200 can be collapsed by moving beams 210a and 210b relative to one
another in
opposite directions, as shown in FIG. 2B, such that beams 210a and 210b
eventually move
to be adjacent to each other and the rails 220 become substantially oblique to
the beams 210.
The beams 210 in the FIG. 2A configuration are approximately parallel to each
other and
spaced further apart than the beams 210 in the folded configuration in the
manner shown in
FIG. 2B.
[0028] A fully collapsed support structure 200 has significantly
less volume than
a support structure 200 in the installation configuration and is easier to
transport to an
installation site. Once support structure 200 is transported to the
installation site, it can be

CA 02717691 2010-10-15
expanded from the folded configuration shown in FIG. 2B to the configuration
shown in
FIG. 2A and then be mounted on tilt tables 320. PV modules 100 can be mounted
to rails
220 when support structure 200 is in the installation configuration of FIG.
2A. It should be
understood that rails 220 can alternatively be rigidly fastened to the beams
210 by fasteners
230 in the FIG. 2A configuration if a collapsible support structure is not
desired or needed.
[0029] System 300 is constructed by installing the support structure
200
comprising a plurality of parallel spaced beams 210 and a plurality of
parallel spaced rails
220 mounted approximately perpendicular to the beams 210. FIG. 3A is a side
view of
beam 210 in accordance with a disclosed embodiment. Beam 210 has pre-punched
holes
290 on the side for PV wire management. Preferably, three 0.375-24 roll thread
or 3/8-24
rivnut holes 290 are pre-punched in beam 210. A set of three holes 290 can be
pre-punched
at pre-determined intervals on beam 210. During on-site installation, wires
attached to PV
module 100 can be mounted through the holes 290. In addition, holes 280 are
pre-punched
on the side of the beam 210 for attachment of the beam 210 to a tilt table 320
(FIGS. 1 and
3E) to achieve a tilt angle a. FIG. 3B shows a cross-sectional view of beam
210 without the
fasteners 230. Beam 210 has a top-hat shaped cross-section formed of two J-
shaped side
walls extending downward perpendicularly from the top surface of beam 210.
[0030] Referring to FIG. 3C, rail 220 has a recessed top surface 270
extending
the length of the rail 220. Rail 220 also includes an opening or hole 275 in
which a fastener,
such as a bolt, screw, nut, rivet or other means of attachment can pass
through to attach rail
220 to beam 210. FIG. 3D shows a cross-sectional view of a rail 220 having a
top mounting
structure 272, side plates 274 extending downward perpendicularly from the
sides of the top
mounting structure 272 and base plates 276 extending outward perpendicularly
from the
bottom of side plates 274.
[0031] Beams 210 in turn may be attached to and supported by tilt
tables 320,
which may be tilted at an angle a for achieving maximum total energy output
for a given
installation. The tilt tables 320 are mounted to support columns 310 as shown
in FIG. 1.
FIG. 3E is a side view of a tilt table 320. Tilt table 320 includes a lower
supporting portion
6

CA 02717691 2010-10-15
350 and an upper mounting portion 360 which can be tilted at installation.
Lower
supporting portion 350 has one or more openings or holes 370 configured for a
fastener,
such as a bolt, screw, nut, rivet or other means of attachment to pass through
to attach to a
support column 310 (FIG. 1). Tilt table 320 can be adjusted to a predetermined
angle
relative to the ground or any other support surface by tightening the fastener
passing through
hole 370 at the predetermined angle. Tilt table 320 also has an opening or
hole 390 at a
corner of lower supporting portion 350 in which a fastener, such as a bolt,
screw, nut, rivet
or other means of attachment can pass through to attach tilt table 320 to
beams 210. Tilt
table 320 can optionally have a connector 380 extending upward,
perpendicularly from an
end of upper mounting portion 360. Connector 380 has an opening or hole 381
configured
for a fastener, such as a bolt, screw, nut, rivet or other means of attachment
to pass through
to secure the tilt table 320 to a beam 210 as shown in FIG. 1.
[0032] The support columns, tilt tables, beams and rails can be made
of a metal
material, such as, galvanized steel or aluminum, or any other suitable
material. The support
structure 200 can be prefabricated and preassembled off-site, thereby reducing
on-site field
labor costs and simplifying the installation process. Preferably, the support
structure 200 is
collapsible in the manner described above for easier transport to the
installation site. The
installation site preferably includes supporting columns 310 mounted into a
support surface
and tilt tables 320 attached to the support columns 310 as shown in FIG. 1. To
install the
support structure 200 when in the configuration shown in FIG. 2A, the beams
210 of support
structure 200 are attached to the tilt tables 320 as described above. The
support structure
200 can be mounted to other mounting surfaces such as building roofs or sides
instead of to
tilt tables 320.
[0033] Referring to FIG. 2A, rail 220 is prefabricated with slider
clips 240, 250
and 260 for holding edge portions of PV modules 100. The distance between the
centers of
each pair of adjacent slider clips 240, 250 and 260 on a rail 220 is
approximately 25.50
inches. The bottom surfaces of slider clips 240, 250 and 260 fit securely
within the recessed
area 270 (FIG. 3C) of rail 220. A top slider clip 240 is mounted at the top of
rail 220 and a
7

=
bottom slider clip 260 is mounted at the bottom of rail 220. Mounted between
the top 240
and bottom 260 slider clips on rail 220 are one or more mid slider clips 250.
The slider clips
240, 250 and 260 are prefabricated and preassembled on the support structure
200 off-site.
Even though FIG. 2A shows that a mid slider clip 250 is mounted near every
intersection of
rail 220 and beam 210, it should be appreciated that a mid slider clip 250 can
be mounted
away from the intersection and multiple mid slider clips can be mounted on
rail 220 between
each pair of beams 210 depending on the dimensions and number of PV modules
100 to be
installed along the rail 220.
[0034] PV modules 100 can be mounted on a rail 220 using two
adjacent pairs of
pre-installed top 240 and mid 250 slider clips, two adjacent pairs of mid 250
and bottom 260
slider clips, or two adjacent pairs of mid 250 slider clips. Alternatively, PV
modules 100
can be mounted on a rail 220 having only top 240 and bottom 260 slider clips.
As explained
in greater detail below, PV module 100 is mounted on the rail 220 by first
sliding an edge
portion of one end of the module 100 into, for example, a top slider clip 240.
Next, the PV
module 100 is laid down on the rail 220. Finally, the opposite edge of the
module 100 is slid
into the slider clip adjacent to the top slider clip 240, which can be a mid
slider clip 250 or a
bottom slider clip 260. Once all of the PV modules 100 are mounted, small gaps
330 and
340 may exist between adjacent PV modules 100 as shown in FIG. 1.
[0035] FIGS. 4A and 4B illustrate, respectively, a perspective view
and a side
view of a top slider clip assembly 240 in accordance with an embodiment
described herein.
Top slider clip assembly 240 has a PV module (solar panel) holding element 489
extending
from one end of a support area 487. Top slider clip assembly 240 components
include a S-
shaped clip frame 400, a clip insert 420 and a fastening element 450 for
attaching the top
slider clip assembly 240 to a rail 220. Clip frame 400 is preferably made of
stainless steel or
other corrosion resistant metals or hard materials. Clip insert 420 serves as
an insulating
material for a PV module 100 and operates to hold an edge portion of PV module
100 in
place on a rail 220. Fastening element 450 attaches the clip assembly 240 to
rail 220.
8

CA 02717691 2010-10-15
[0036] Top slider clip frame 400 is illustrated in more detail in
FIGS. 5A and 5B.
FIG. 5A illustrates a perspective view of clip frame 400 and FIG. 5B
illustrates a side view
of clip frame 400. Clip frame 400 is formed as an integral structure. The
integral structure
of clip frame 400 has a flat bottom extension 501 with an opening or hole in
which a
fastener 450, such as a bolt, screw, nut, rivet or other means of attachment
can pass through
to attach assembly 240 to rail 220. In this example embodiment, fastener 450
is a 0.25-20
socket head cap bolt 451. Other elements such as a washer 452 and a gasket 453
may also
be included in the fastening element 450. The bolt 451 is preferably torqued
to a minimum
of 100 in-lbs during pre-fabrication of the support structure 200. Unlike the
conventional
systems of mounting a PV module, the tightening of the slider clips can be
performed prior
to arriving at the installation site, thus, simplifying the on-site
installation, especially of
large-scale PV systems installations.
[0037] As shown in FIG. 5B, an emboss layer 506 may cover at least a
portion of
the top surface of bottom extension 501. A vertical sidewall 503 of the S-
shaped clip frame
400 connects the bottom extension 501 and a top extension 502. Top extension
502 extends
from sidewall 503 in the opposite direction from the bottom extension 501.
Protruding from
the top surface of top extension 502 are at least two angled structures such
as, for example,
tiger teeth 504, for holding the clip insert 420 in place with the clip frame
400. In this
example embodiment, the bottom extension 501 is approximately one inch long
and two
inches wide and the top extension 502 is approximately 1.25 inches long and
two inches
wide. The vertical sidewall 503 is preferably about 0.85 inch tall. The top
extension 502
and sidewall 503 forms an angle 3 equal to or less than 90 degrees, preferably
84.1 degrees.
The angle of the tiger teeth 504 in conjunction with the angle [3 of the top
extension 502
operate to hold the clip insert 420 in place with the clip frame 400.
[0038] FIGS. 6A and 6B illustrate, respectively, a perspective view
and a side
view of the top slider clip insert 420. Clip insert 420 has a flat middle
section 600 that sits
directly under the bottom extension 501 of clip frame 400. Extending from one
end of the
middle section 600 is a C-shaped holding element 610 for holding an edge
portion of PV
9

CA 02717691 2010-10-15
module 100. At the other end of the middle section 600 is a curved tail
section 650. Clip
insert 420 is preferably made of fire resistant silicone rubber, for example,
Ethylene
Propylene Diene Monomer (EPDM) rubber. It should be appreciated that other
types of
rubber and insulating material may be used provided that the hardness of the
material used
preferably has a shore A durometer of between 50 and 70.
[0039] The C-shaped holding element 610 has a substantially flat
bottom section
611, a top section 612 and a vertical barrier 613 connecting the bottom
section 611 and the
top section 612 to form a channel for holding an edge portion of PV module
100. The
vertical barrier 613 is preferably 0.73 inch tall. The bottom surface of top
section 612 and
the top surface of bottom section 611 are preferably surfaces which resist PV
module
movement. In this example embodiment, the surfaces are at least partially
covered with
angled teeth 615, which preferably run the width of sections 611 and 612. The
teeth 615 are
angled towards the barrier 613 such that the counteracting teeth operate to
hold the PV
module 100 in place between sections 611 and 612. Moreover, as explained
above, since
the PV module 100 will be installed at a tilt angle, its weight and the
friction caused by the
EPDM rubber also help to frictionally retain the PV module 100 in place.
[0040] As shown in FIGS. 4A and 4B, clip insert 420 is integrally
connected to
clip frame 400. In this example embodiment, the C-shaped holding element 610
(FIG. 6A)
of clip insert 420 fits snuggly within the area formed by the top extension
502 and the
sidewall 503 (FIG. 5B) of clip frame 400. Referring to FIG. 6B, the top
section 612 of clip
insert 420 includes a curved element such as, for example, a hook element 616,
that is
designed to engage with the tiger teeth 504 on the top extension 502 of the
clip frame 400.
Adhesives and other fastening means can be optionally added to secure the clip
insert 420 to
the clip frame 400.
[0041] FIGS. 7A and 7B illustrate, respectively, a perspective view
and a side
view of a bottom slider clip assembly 260 in accordance with an embodiment
described
herein. Bottom slider clip assembly 260 shares similar features to top slider
clip assembly
240. Clip assembly 260 has a PV module (solar panel) holding element 789
extending from

CA 02717691 2010-10-15
one end of a support area 787. Clip assembly 260 components include a S-shaped
clip
frame 700, a clip insert 720 and fastening element 750 for attaching the
bottom slider clip
assembly 260 to a rail 220. Some clip assembly 260 components that are
identical to clip
assembly 240 components such as, for example, fastening element 750 are not
described
below. The differences between clip assemblies 260 and 240 are explained in
more detail
below.
[0042] Bottom slider clip frame 700 is illustrated in more detail in
FIGS. 8A and
8B. FIG. 8A illustrates a perspective view of clip frame 700 and FIG. 8B
illustrates a side
view of clip frame 700. Clip frame 700 is preferably made of the same material
as clip
frame 400. Clip frame 700 is formed as an integral structure. Similar to clip
frame 400, the
integral structure of clip frame 700 has a flat bottom extension 801 that
extends from one
end of sidewall 803. The bottom extension 801 has an opening or hole in which
a fastener,
such as a bolt, screw, nut, rivet or other means of attachment can pass
through to attach
assembly 260 to rail 220. The top 802 and bottom 801 extensions of the bottom
slider clip
frame 700 are preferably shorter than the top 502 and bottom 501 extensions of
the top
slider clip frame 400. In this embodiment, the bottom extension 801 is
approximately 0.81
inch long and two inches wide and the top extension 802 is approximately 0.48
inch long
and two inches wide. Emboss layer 806 optionally covers at least a portion of
the top
surface of bottom extension 801 as shown in FIG. 8B. The top extension 802 and
sidewall
803 forms an angle p equal to or less than 90 degrees, preferably 80.0
degrees. Protruding
tiger teeth 804 located on the top surface of top extension 802 serves the
same function as
tiger teeth 504 of clip frame 400.
[0043] FIGS. 9A and 9B illustrate, respectively, a perspective view
and a side
view of the bottom slider clip insert 720. Clip insert 720 is preferably made
of the same
material as clip insert 420. Similar to clip insert 420, clip insert 720 has a
flat middle
section 900 that sits directly under the bottom extension 801 of clip frame
700. Extending
from one end of the middle section 900 is a C-shaped holding element 910 for
holding an
11

CA 02717691 2010-10-15
edge portion of PV module 100. At the other end of the middle section 900 is a
curved tail
section 950.
[0044] The C-shaped holding element 910 has a substantially flat
bottom section
911, a top section 912 and a vertical barrier 913 connecting the bottom
section 911 with the
top section 912 to form a channel for frictionally holding an edge portion of
PV module 100.
The vertical barrier 913 is preferably 0.73 inch tall. The bottom section 911
is preferably
shorter than the bottom section 611. The bottom surface of top section 912 and
the top
surface of bottom section 911 are preferably resistant to PV module movement.
The
surfaces, for example, may be partially covered with angled teeth 915. The
teeth 915
preferably run the width and length of sections 911 and 912 and are angled
towards the
barrier 913 such that the counteracting teeth operate to hold an edge portion
of PV module
100 in place between sections 911 and 912.
[0045] As shown in FIG. 7A, clip insert 720 is integrally connected to
clip frame
700. In this example embodiment, the C-shaped holding element 910 of clip
insert 720 fits
snuggly within the area formed by the top extension 802 and the sidewall 803
of clip frame
700. The top section 912 of clip insert 720 includes a curved element such as,
for example,
a hook element 916 that is designed to engage with the tiger teeth 804 on the
top extension
802 of the clip frame 700.
[0046] Having described example embodiments of the top slider clip
assembly
240 and the bottom slider clip assembly 260, an example embodiment of the mid
slider clip
assembly 250 is now described. FIGS. 10A and 10B illustrate, respectively, a
perspective
view and a side view of an example embodiment of mid slider clip assembly 250.
Mid
slider clip assembly 250 has two PV module holding elements 1088 and 1089,
each
extending from opposite ends of a common support area 1087 for frictionally
holding an
edge portion of a PV module 100. Holding element 1088 is similar to holding
element 489
of clip assembly 240. Holding element 1089 is similar to holding element 789
of clip
assembly 260. Mid slider clip assembly 250 components include a clip frame
1000, a clip
insert 1020 and fastening element 1050 for attaching the mid slider clip
assembly 250 to rail
12

CA 02717691 2010-10-15
220. Fastening element 1050 is similar to fastening elements 450 and 750. The
differences
and similarities between assemblies 240, 260 and 250 are explained in more
detail below.
100471 FIGS. 11A and 11B illustrate, respectively, a perspective view
and a side
view of the mid slider clip frame 1000. Clip frame 1000 is formed as an
integral structure.
The integral structure of clip frame 1000 is essentially the combination of
the top slider clip
frame 400 and the bottom slider clip frame 700 having a common bottom
extension 1001.
Similar to clip frames 400 and 700, the common bottom extension 1001 has an
opening or
hole in which a fastener, such as a bolt, screw, nut, rivet or other means of
attachment can
pass through to attach assembly 250 to rail 220. Emboss layer 1106 covers at
least a portion
of the top surface of the common bottom extension 1001. In this example
embodiment, the
common bottom extension 1001 has identical dimensions to the bottom extension
801 of
clip frame 700. However, it should be understood that the common bottom
extension 1001
can also have the same dimensions as the bottom extension 501 of clip frame
400. It should
be appreciated that the width of the common bottom extension 1001 is
preferably the same
as extensions 801 and 501, but the length of the common bottom extension 1001
can be any
arbitrary length.
100481 Extending perpendicularly from one end of the common bottom
extension
1001 is sidewall 1503 and from the other end is sidewall 1803. The vertical
sidewalls 1503
and 1803 are preferably about 0.85 inch tall. Sidewall 1503 has a top
extension 1502 that
extends perpendicularly from the top of sidewall 1503 and away from the common
bottom
extension 1001. Similarly, sidewall 1803 has a top extension 1802 that extends

perpendicularly from the top of sidewall 1803 and away from the common bottom
extension
1001. The top extension 1802 is preferably shorter than the top extension
1502. The
common bottom extension 1001, the sidewall 1503 and the top extension 1502
together
form a S-shaped clip frame similar to the S-shaped top slider clip frame 400.
Likewise, the
common bottom extension 1001, the sidewall 1803 and the top extension 1802
together
form a S-shaped clip frame similar to the S-shaped bottom slider clip frame
700. The top
surfaces of top extensions 1502 and 1802 include respectively protruding
angled structures
13

CA 02717691 2010-10-15
such as, for example, tiger teeth 1504 and 1804. Clip frame 1000 is preferably
made of the
same material as clip frames 400 and 700.
10049] As shown in FIG. 11B, the top extension 1502 and sidewall 1503
form an
angle 13 equal to or less than 90 degrees, preferably 84.1 degrees. Likewise,
the top
extension 1802 and sidewall 1803 form an angle p equal to or less than 90
degrees,
preferably 80.0 degrees. The difference in angle 13 from angle p results in
the height from
the common bottom extension 1001 to the outer tip of the top extension 1502 to
be relatively
equal to the height from the common bottom extension 1001 to the outer tip of
the top
extension 1802. In this example embodiment, this height is roughly 0.69
inches.
100501 FIGS. 12A and 12B illustrate, respectively, a perspective view
and a side
view of the mid slider clip insert 1020. Clip insert 1020 is preferably made
of the same
material as clip inserts 420 and 720. Similar to the clip inserts 420 and 720,
clip insert 1020
has a flat middle section 1200 that sits directly under the common bottom
extension 1001 of
clip frame 1000. However, unlike the other clip inserts 420 and 720, the mid
slider clip
insert 1020 does not have a tail section. Rather, extending from one end of
the middle
section 1200 is a C-shaped holding element 1261 and from the other end of the
middle
section 1200 is a C-shaped holding element 1291. Clip insert 1020 is designed
to
frictionally hold the edges of two PV modules 100 one in each of the C-
shaped holding
elements 1261 and 1291.
100511 Similar to the C-shaped holding element 610 of the top slider
clip insert
420, the C-shaped holding element 1261 has a substantially flat bottom section
1211, a top
section 1212 and a vertical barrier 1213 connecting the bottom section 1211
with the top
section 1212 to form a channel for frictionally holding an edge portion of a
PV module 100.
The bottom surface of top section 1212 and the top surface of bottom section
1211 are
resistant to PV module movement. In this example embodiment, the surfaces are
at least
partially covered with angled teeth 1215. The teeth 1215 preferably run the
width of
sections 1211 and 1212 and are angled towards the barrier 1213 such that the
counteracting
teeth operate to hold an edge portion of PV module 100 in place between
sections 1211 and
14

CA 02717691 2010-10-15
1212. The C-shaped holding element 1291 is like the C-shaped holding element
910 of the
bottom slider clip insert 720. C-shaped holding element 1291 has a
substantially flat bottom
section 1221, a top section 1222 and a vertical barrier 1223 connecting the
bottom section
1221 with the top section 1222 to form a channel for frictionally holding an
edge portion of
PV module 100. The bottom surface of top section 1222 and the top surface of
bottom
section 1221 are surfaces which resist PV module movement. In this example
embodiment,
the surfaces are at least partially covered with angled teeth 1225. The teeth
1225 preferably
run the width and length of sections 1221 and 1222 and are angled towards the
barrier 1223
such that the counteracting teeth operate to hold an edge portion of PV module
100 in place
between sections 1221 and 1222. The bottom section 1221 is shorter than the
bottom
section 1211 similar to the difference in length between the bottom sections
611 and 911.
Moreover, the top section 1222 is shorter than the top section 1212. Thus, the
C-shaped
holding element 1291 will be referred to as the short end of the mid slider
clip assembly 250
while the C-shaped holding element 1261 will be referred to as the long end of
the mid
slider clip assembly 250. Clip assembly 240 has only a long end (i.e., holding
element 610)
while clip assembly 260 has only a short end (i.e., holding element 910).
[0052] As shown in FIG. 10A, clip insert 1020 is integrally
connected to clip
frame 1000. In this example embodiment, the common bottom extension 1001 of
clip frame
1000 is attached to the top surface of middle section 1200 and the C-shaped
holding
elements 1261 and 1291 fit snuggly within the respective area formed by the
top extension
1502 and sidewall 1503 and the top extension 1802 and sidewall 1803. Similar
to the
designs of the top sections 612 and 912, the top sections 1212 and 1222
include respective
curved elements such as, for example, hook elements 1216 and 1226, for
engaging with
respective tiger teeth 1504 and 1804.
[00531 The mid slider clip assembly 250 is mounted on rail 220
such that its
short end faces the PV module holding element 489 of the top slider clip
assembly 240. The
long end of mid slider clip assembly 250 then faces the PV module holding
element 789 of
the bottom slider clip assembly 260. Alternatively, it should be understood
that the mid
=

CA 02717691 2010-10-15
slider clip assembly 250 can be mounted on rail 220 in the opposite direction
such that its
long end faces towards the top of rail 220 and its short end faces the bottom
of rail 220.
However, in this alternative embodiment, the location of the slider clip
assemblies 240 and
260 would have to be swapped such that the clip assembly 240 is now mounted on
the
bottom end of rail 220 and the clip assembly 260 is now mounted on the top end
of rail 220.
The significance of the mounting direction for clip assemblies 240, 250 and
260 will be
explained in connection with FIG. 13 below.
[0054] FIG. 13 illustrates a method for installing a plurality of PV
structures on
the prefabricated support structure 200 described above. FIGS. 14A-14C
illustrate in
process flow a method for installing a single PV structure on the support
structure using top
and mid slider clip assemblies in accordance with an embodiment described
herein.
Although the steps below are described with respect to the PV module 100, it
should be
understood that the process applies to any kind of PV structure including the
framed PV
structure described below in connection with FIG. 16.
[0055] At step 1300, the prefabricated support structure 200 having
preassembled slider clips is setup at an installation site. Once the support
structure is setup,
the PV modules 100 are mounted on the module rails 220 using slider clips 240,
250 and
260. A PV module 100 is selected for installing on the support structure 200
at step 1310.
At step 1320 and illustrated in FIG. 14A, one end of the selected PV module
100 is slid into
the long end of a clip assembly, such as, for example, C-shaped holding
element 610 of the
top slider clip assembly 240. The PV module 100 has to be slid far enough in
section 610
such that at step 1330, the PV module 100 can be laid flat on rail 220 as
shown in FIG. 14B.
At step 1340 and illustrated in FIG. 14C, the other end of the PV module 100
is then slid
into the short end of an adjacent slider clip assembly, such as, for example,
C-shaped
holding element 1291 of mid slider clip assembly 250. The PV module 100 is
thus
frictionally held in place by the slider clips holding it. At step 1350, a
determination is made
as to whether all PV modules 100 have been installed. The process ends if all
PV modules
16

CA 02717691 2010-10-15
100 have been mounted. Otherwise, the process returns to step 1310 for the
selection of the
next PV module to install on rail 220.
[00561 It should be understood that regardless of the pair of adjacent
slider clips
used for installing a PV module 100, an edge of the PV module 100 is slid into
the slider
clip with the longer clip frame and clip insert before the opposite edge of
the PV module 100
is slid into the other slider clip with the shorter clip frame and clip
insert. The lengths of the
clip holding elements and the distance between the mounting locations of
adjacent clip
assemblies on a rail 220 are designed to simplify the installation process and
to hold an edge
portion of PV module 100.
[0057] FIG. 15 is a perspective view of a plurality of framed PV
modules 100
supported by a common carrier structure 1500 in accordance with another
disclosed
embodiment. The carrier structure 1500 is a lightweight, cartridge-like PV
module carrier
structure that provides structural support, contains and supports an array of
PV modules
1520a-h and enables their electrical connections. The carrier 1500 is
approximately two
inches thick and made of either synthetic or natural structural material,
including, but not
limited, to aluminum, rolled steel, or other metals and plastics. The PV
modules 1520a-h
(1520g is not shown) are each held in place by being snapped, clipped, or
otherwise securely
seated in a recessed area such as 1510g. The PV modules 1520a-h are preferably
mounted
in the carrier structure 1500 before transporting them to an installation
site, so all that needs
to be done at the installation site is to mount the carrier structure 1500 to
a support structure.
Although an array of eight PV modules 1520a-h is shown in FIG. 15, it is
understood that
any number or arrangement of solar panels could be mounted on and supported by
a carrier
structure 1500. A pre-wired common bus or cable system for transmitting
harvested solar
electricity may be integral to the carrier structure 1500.
[0058] FIG. 16 is a perspective view of a support structure 1620 of a
mounting
system that can be used to install the carrier structure 1500. The mounting
system can be
constructed by installing the support structure 1620 comprising a plurality of
parallel spaced
beams 1610 mounted to support columns via tilt tables similar to those
illustrated in FIGS.
17

CA 02717691 2010-10-15
lA and 1B. Like the mounting system 300 described above, parallel spaced rails
1600 are
mounted perpendicularly to beams 1610 using fasteners 1630. Prefabricated
slider clips
1640, 1650 and 1660 are preassembled on rails 1600. It should be understood
that slider
clips 1640, 1650 and 1660 have substantially the same overall design as slider
clips 240, 250
and 260, respectively. Slider clips 1640, 1650 and 1660 each frictionally hold
an edge
portion of the carrier structure 1500, which contains an array of PV modules
100 rather than
a single PV module 100. Since the carrier structure 1500 is typically thicker
and heavier
than a frameless PV module, slider clips 1640, 1650 and 1660 each have a
sidewall and a
barrier sufficiently tall to hold an edge portion of the carrier structure
1500. Accordingly,
each slider clip 1640, 1650 and 1660 will have a clip frame with a taller
sidewall than
sidewalls 503 and 803 and a clip insert with a taller barrier than barriers
613 and 913. Each
slider clip 1640, 1650 and 1660 optionally has a clip insert with a
respectively longer C-
shaped holding element so as to compensate for the wider and heavier carrier
structure 1500.
[0059] It should be understood that the process of installing the
carrier structure
1500 on the preassembled support structure 1620 is similar to the process of
installing the
PV module 100 on the support structure 200. Given that the carrier structure
1500 is
generally longer, wider and heavier than a frameless PV module, in this
example
embodiment and as shown in FIG. 16, the carrier structure 1500 is inserted
into four
adjacent pairs of slider clips. For example, the carrier structure 1500 would
be inserted into
the long ends of four mid slider clip assemblies 1650a-d before being inserted
into the short
end of four adjacent mid slider clip assemblies 1650e-h. The slider clips are
mounted on the
beams 1610 such that a slider clip frictionally holds the carrier structure
1500 at
approximately the center of each solar panel as shown in FIG. 16. Even though
the
embodiment is described with a set of eight slider slips holding a carrier
structure 1500
having a 4 by 2 array of solar panels, it should be appreciated that any
number of slider clips
can be used depending on the size and arrangement of the carrier structure.
[0060] FIG. 17A illustrates a module rail 1700 with an integrated
slider clip in
accordance with another embodiment. Similar to rail 220, rail 1700 has a top
plate 1710,
18

side plates 1720 extending downward perpendicularly from the sides of top
plate 1710 and
base plates 1730 extending outward perpendicularly from the bottom of side
plates 1720.
Rail 1700 is also integrated with a top slider clip 1740, a mid slider clip
1750 and a bottom
slider clip 1760. FIG. 17B illustrates an end view of rail 1700 at the cross
section A-A'. It
will be readily appreciated by those skilled in the art that slider clips
1740, 1750 and 1760
operate similarly to slider clip assemblies 240, 250 and 260, respectively.
However, unlike
slider clip assemblies 240, 250 and 260 which are fabricated separately from
rail 220 and
mounted to rail 220 using fasteners, slider clips 1740, 1750 and 1760 are
formed integrally
with rail 1700. Slider clips 1740, 1750 and 1760 can be manufactured using
punch forming,
press forming, or any other suitable metal forming technique. The clips can be
formed into
the material that forms the rail concurrent with or subsequent to forming the
rail itself. A
resilient material can optionally be added to the inside surfaces of the clips
to engage with
an edge portion of a PV structure. Optionally, a clip insert made of a
resilient rubber, for
example, EPDM rubber, can be attached to the inside surfaces of the clips as
shown in FIG.
17C for the mid slider clip 1750 to hold the edge portion of a PV structure.
It will be readily
appreciated by those skilled in the art that rail 1700 can be used in a
photovoltaic structure
mounting system such as mounting system 300 by replacing rail 220 and clip
assemblies
240, 250 and 260 with rail 1700. It should also be readily appreciated that
the process of
installing a PV module 100 on a mounting system using the clip integrated rail
1700 is
similar to the installation process described in FIG. 13 in connection with
the support
structure 200. Furthermore, the process of installing a carrier structure 1500
on a mounting
system using the clip integrated rail 1700 is similar to the installation
process described
above in connection with the support structure 1620.
[0061] Disclosed embodiments substantially reduce labor costs
associated with
the fabrication of PV mounting systems and reduce the time required for on-
site mounting of
PV modules. The slider clips used in the disclosed PV mounting systems can be
fully
tightened to a prefabricated module rail or other surface in a controlled
environment and
shipped to an installation site for installation of the PV modules. Large
numbers of PV
modules can be mounted quickly on the support structure using the disclosed
slider clips.

[0062] While the invention has been described in detail in connection
with
embodiments known at the time, it should be readily understood that the
claimed invention
is not limited to the disclosed embodiments. Rather, the embodiments can be
modified to
incorporate any number of variations, alterations, substitutions, or
equivalent arrangements
not heretofore described. For example, while the disclosed embodiments of the
slider clips
are described in connection with module rails, beams, tilt tables and support
columns, the
embodiments can be mounted on other support surfaces or structures and other
connecting
means besides fasteners can be used to attach these embodiments to the support
surfaces and
structures. Furthermore, while the disclosed embodiments of the mounting
system are
described in connection with framed or frameless PV modules, the disclosed
slider clips can
be modified to support any dimension and type of PV structures including
partially framed,
foldable and flexible PV modules.
